Control module MDP-1_PLUS/M/420 1 input, power supply 230V, output 4-20mA, RS-485 port, IP54 housing MDP-1.PLUS/M/420

Control module for gas detection systems

This control module, also known as MDP-1.plus/M/420, is an advanced device designed to work with various types of gas detectors – measurement (DEX/P, DG/P) and threshold (DEX/F, DEX/A, DG/F, DG.EN). It serves to ensure safe and reliable monitoring of gas concentrations in various industrial and commercial applications. Designed for both professional installers and end-users, it offers configuration flexibility and easy integration with existing systems.

Functionality and application

MDP-1.plus is a complete set – a measurement module MDP-1.A/T, a 12V= power supply, and an installation switch – housed in a durable IP54-rated enclosure. It not only powers the detector but also cyclically measures and controls the signals from it. If the established gas concentration thresholds are exceeded, the module activates optical signaling and alarm outputs – relay and voltage. Additionally, it can optionally be equipped with an RS-485 port (MODBUS RTU protocol) for remote communication and an analog output 4-20mA or 2-10V for integration with control systems.

The device finds application in:

• Local gas detection systems for toxic, explosive gases, or oxygen.
• Individual protection of rooms or industrial equipment.
• Distributed gas detection systems – an ideal solution for facilities with a large area.

Features and benefits

• Versatility: Compatible with a wide range of Gazex detectors (DEX/P, DG/P, DEX/F, DEX/A, DG/F, DG.EN).
• Configuration: Setting alarm thresholds (including “window” detection) directly on the module’s front panel – without the need to connect to a computer.
• Signaling: Clear optical signaling of signal status and control outputs using LEDs.
• Outputs: Availability of voltage alarm outputs 12V= for powering acoustic and optical signaling devices and relay outputs for controlling fans or contactors.
• Communication: Optional RS-485 port enables remote monitoring and configuration using the dedicated “DETnet View” software.
• Easy installation: Removable, screwless terminals facilitate connection of wires – both stranded and solid core (without the need for ferrules).
• Durable housing: The IP54-rated enclosure provides resistance to weather conditions and dust – ideal for use in harsh industrial environments.
• Connection check: The module checks the connection status with the detector and signals any circuit breaks.

The MDP-1 PLUS module is a ready-to-install solution providing comprehensive protection against hazards related to the presence of gases in the monitored environment. Its flexibility and ease of configuration make it an ideal choice for both professionals and end-users looking for a reliable gas detection system.
